The **M2AS1-6222-R/N** is a specialized electronic component, typically categorized as a **Modular Jack (RJ45)** connector integrated with internal magnetics. These components are commonly referred to as "MagJacks." Below is a detailed breakdown of its specifications, internal parts, and functionality. --- ### 1. General Specifications This part is designed for Ethernet networking applications, providing the physical interface between the networking cable and the Printed Circuit Board (PCB). | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C) | | **Integration** | Integrated Magnetics (Transformer/Chokes) | | **Speed Support** | 10/100 Base-T (Fast Ethernet) | | **Configuration** | Single Port, Right Angle (Tab-Down) | | **Mounting Type** | Through-Hole (THT) | | **Shielding** | Metal Shield with EMI fingers | --- ### 2. Internal Electronic Sub-components The "integrated magnetics" aspect means the connector is not just a plastic housing but contains a small circuit inside: * **Isolation Transformer:** Provides electrical isolation (usually 1500Vrms) to protect the equipment from voltage surges on the network line. * **Common Mode Chokes:** Filters out electromagnetic interference (EMI) and noise from the differential signals. * **Termination Resistors:** Usually 75-ohm resistors (Bob Smith Termination) to reduce reflections and improve signal integrity. * **High-Voltage Capacitor:** Decouples the chassis ground from the signal ground to manage ESD (Electrostatic Discharge). --- ### 3. Physical & Material Composition The build quality of the M2AS1 series focuses on durability and conductivity: 1. **Housing:** High-temperature thermoplastic (UL 94V-0 rated). 2. **Contacts:** Copper alloy with gold plating (often 30μ" or 50μ") on the mating area to prevent corrosion and ensure low contact resistance. 3. **Shield:** Stainless steel or copper alloy with nickel plating for grounding and EMI protection. 4. **LEDs (If applicable):** Many variants include integrated Green/Yellow LEDs to indicate Link and Activity status. --- ### 4. Part Number Breakdown (Typical) * **M2AS:** Series designation for Modular Jacks with Magnetics. * **6222:** Specific internal schematic and mechanical footprint code. * **R:** Often denotes RoHS Compliance (Lead-Free). * **N:** Often denotes "Non-LED" or a specific plating/packaging variation depending on the manufacturer (usually M-Tek or similar vendors). --- ### 5. Application Circuit When designing with this part, it is typically placed between the **Ethernet PHY (Physical Layer Chip)** and the **RJ45 cable input**. ```c [Ethernet PHY] <---> [M2AS1-6222-R/N (Magnetics)] <---> [Cat5e/6 Cable] ```
